Review on Vacuum Hose Coupler Accessory Counterclockwise by Erica Rogers

I bought this to possibly connect a 1-7/8" hard vacuum hose to a hard/standard 2-1/2" To connect inch vacuum hose. as there is literally a black hole of adapters filling that role to increase size. Either way, this connector will work, but you'll need to wrap a few stitches of tape around the outside. Installation: 1-7/8 Raw Hose - This adapter is a female vacuum pump coupler - standard 2-1/2" vacuum hose. Hope this helps. If anyone finds this adapter I'm looking for that doesn't require duct tape please let me know to know!
